Types of Bearings and What to Use Them For Jeremy S Cook Jeremy is an engineer with 10 years experience at his full-time profession, and has a BSME from Clemson University.
Different bearing types have different operating speed limits. Speed is typically specified as maximum relative surface speeds, often specified ft/s or m/s. Rotational bearings typically describe performance in terms of the product DN where D is the mean diameter (often in mm) of the bearing and N is the rotation rate in revolutions per minute.
There are many different types of bearings, each used for specific purposes and designed to carry specific types of loads, radial or thrust. Here, we’ll look at the 6 most popular types: plain bearings, rolling element bearings, jewel bearings, fluid bearings, magnetic bearings, and flexure bearings.
The most common bearing application is the Ball Bearing . Ball Bearing types permit smooth, low-friction movement between two or more surfaces. This movement is either rotary (shaft rotating within a mount) or linear (one surface moving along another). Bearings , are anti-friction devices, each having different anti-friction characteristics.
In addition to the list below, each section such as worm gear, rack and pinion, bevel gear, etc. has its own additional explanation regarding the respective gear type. If it is difficult to view PDF, please consult these sections. It is best to start with the general knowledge of the types of gears as shown below.
Types & Functions Of Bearings for Bridges Function Of Bearings. Bridge bearings are used to transfer forces from the superstructure to the substructure, allowing the following types of movements of the superstructure: Translation movements; are displacements in vertical and horizontal directions due to in-plane or out-of-plane forces like wind and self weight.

Types of grease in motor bearings Some motor manufacturers have used polyurea-based grease—which performs well at high temperatures (over 250 F) and high speeds (10,000 rpm or higher)—almost exclusively for more than 30 years.
Four-Point Contact Ball Bearings: These bearings, with 35° angles, are optimal for heavy axial loads. The inner ring is split in two, allowing the bearing to hold a significant axial load in a single direction. A primary differentiating factor between different angular contact bearings is the presence (and type) of seals and shields.
Wheel bearings allow the rotation of the wheel (driven or non-driven), relative to the chassis of the car, while supporting the loads applied to the wheel. NTN-SNR has developed different types of bearings for car manufacturers, depending on the vehicle and the performance requirements.
Different Bearing types. There are many types of bearings, each used for different purposes either singularly or in combinations. These include ball bearings, roller bearings, ball thrust bearings, roller thrust bearings and tapered roller thrust bearings. Ball bearings. Ball bearings, as shown to the left, are the most common type by far.
Lubrication, especially circulating oil will also remove heat from the bearing. There are two basic types of bearing lubricants readily available: Oil and Grease. The former is fairly simple to understand being a free-flowing liquid, while the latter is a little more complex.
Most electric motors in industrial facilities consist of rolling element bearings, either ball bearings or roller bearings. We will explore these different types of bearings and sealing methods in this article. Ball Bearing. Used in direct coupled applications. These can handle axial as well as radial loads.

significantly from ball bearings and other types of roller bearings. The rolling elements and both races slant inward, much like a cone. If you extend a line along the surface of the races and rollers, and also draw one through the bearing’s axis, those lines would all meet at a common point (fig. 3).
